I'm not part of the development team but from what I understand, blocking these blocks is like a repetitive game where one blocks the other, then the other creates an update to unblock the block, etc. I understand adfly is still keeping up with these matches though I'm not sure I've heard of Ublock before till now.

Seems best to have a script that blocks content unless you turn off adblock

Actually the first thing adfly admin can do is to write an formal email to Ublock, requesting them to stop decode adfly. Adfly may not have a legal stand here but a formal email request can most likely put them off. If it fail, the development team will have to come in.
